Also known as a cold reset, a cold reset can be helpful if unable to Telnet to the print server due to an IP address conflict or if unable to see it in HP Web Jetadmin, the Install Network Printer Wizard, or one of the other utilities listed below.
A cold reset will clear any previous IP address or passwords as well as resetting the printer configuration back to factory defaults. The factory defaults include a TCP/IP address of either 169.254.x.x or 192.0.0.192. Some print servers may show the TCP/IP address as 0.0.0.0 if a LAN cable is not connected, or if the print server cannot detect the network connection due to a bad cable, hub, or LAN link speed configuration problem.
Here are some general steps that work for most printers and print servers. Additional cold reset steps may be found in the printer's manual or CD-ROM documents or on the HP Web site noted in the hyperlink above.
